-3x + 4y = 12

get into y = mx +b form

-3x +3x + 4y = 12 + 3x

4y = 3x + 12

4y/4 = (3x+12)/4

y = 3/4x + 3

y = mx +b, where m = slope, b = y-intercept

SO our slope is 3/4, and our y-intercept is (0, 3)

Put into form y = mx + b

- 3x + 4y = 12

4y = 3x + 12

y = 3/4x + 12/4

y = 3/4x + 3

Slope is 3/4 and y intercept 3

-3x + 4y = 12 =>

4y = 3x+12 =>

y = (3/4)x + 3

y = a*x + b , where a is the slope and b is the y interceptor

You should be able to figure it out know ; )

Write as an equation:-

-3x + y = 12

y = 3x + 12

slope = 3

y intercept at point (0,12)
